Jiffy Lube is here to help you with all of your automotive needs. We can handle your regular maintenance as well as problems that arise. One common problem we see is a faulty mass airflow sensor. Learn the symptoms of issues with this component so you know when to have it serviced.
Understanding the Mass Airflow Sensor
Before getting into the signs of a faulty mass airflow sensor, you may want to know what this component is. After all, understanding its importance will help you understand why it’s so important to replace or repair it.
The mass airflow sensor is a crucial part of your fuel injection system. It is solely responsible for checking the air flowing into your engine intake. This component ensures your fuel-to-air ratio is ideal, so your car functions properly.
With that in mind, how do you know you have a faulty mass airflow sensor?
Check Engine Light
The first indication you have a faulty mass airflow sensor will likely come from your check engine light. Of course, there are also plenty of other reasons that this light may come on. So, anytime your check engine light turns on, you must get maintenance as soon as possible.
Rough Running or Misfiring
The engine won’t receive the proper airflow if you have a faulty mass airflow sensor. This, in turn, can lead to your car running roughly or the engine misfiring. That happens because the imbalance means that your powertrain control module can’t determine how much fuel your engine needs to run. It can also lead to uneven combustion.
Trouble Starting or Turning Over
Sometimes, the engine won’t misfire or run rough because it won’t start or turn over at all. This is another issue caused by an imbalanced air-to-fuel ratio. Your car won’t start until you fix the faulty mass airflow sensor.
Black Smoke From the Exhaust
Another common indication that something is wrong with the mass airflow sensor is black smoke coming out of the exhaust. This indicates that the air mass within your engine intake is not just imbalanced but potentially at a dangerous level.
